A method for operating an internal combustion engine having at least one triggerable intake valve and at least one triggerable discharge valve, in which the internal combustion engine is directly started in a start-up operating mode and, following the start, is operated in at least one other operating mode. A starting discharge instant of a discharge valve of the internal combustion engine that is used during the start-up operating mode is retarded in time with respect to a standard discharge instant so as to improve the direct start-up characteristics of the internal combustion engine. In addition, to further improve the direct start-up characteristics, it is possible to retard a closing instant of an intake valve that is used during the start-up operating mode with respect to a standard closing instant.
A method for operating an internal combustion engine having at least one triggerable intake valve and at least one triggerable discharge valve, comprising:
An internal combustion engine, comprising:
A control device for an internal combustion engine having at least one triggerable intake valve and at least one triggerable discharge valve that is directly started in a start-up operating mode and, following the start, is operated in at least one additional operating mode, comprising:
A computer program for a control device for an internal combustion engine having at least one triggerable intake valve and at least one triggerable discharge valve that is directly started in a start-up operating mode and, following the start, is operated in at least one additional operating mode, comprising:
